Fuji Electric SC‑E4 (including SC‑E4/G DC type) 3‑pole electromagnetic contactor. This is a main model in the SC‑E series with an 80A frame, used for industrial motor control.

Key Rated Parameters

  1. Motor Power (AC‑3): 22kW at 200–240V; 40kW at 380–440V
  2. Rated Operational Current: 80А (AC‑3); 105A for resistive load (AC‑1)
  3. Operation Type: AC operation SC‑E4; DC coil SC‑E4/G (например. DC24V, 110 В постоянного тока)
  4. Mounting: 35мм DIN-рейка / screw fixing; dimensions 67×130×112 mm; weight approx. 1.4 кг
  5. Сертификаты: Compliant with IEC, UL, CSA; marked with CE; finger‑safe terminals for electric shock protection

Структура & Функции

3‑pole main circuit, standard without auxiliary contacts (auxiliary modules such as SZ‑AS1T can be side‑mounted to expand 1a1b / 2a / 2b)

Direct‑connect main terminal design for easier wiring; safety structure to prevent exposed live parts

Coil options: 110 В переменного тока, 220 В переменного тока, AC380В, DC24V, 110 В постоянного тока; DC type (/Г) suitable for unstable grids or DC control circuits

Compatible thermal overload relay: TK‑E3 series, for overload, locked‑rotor, and phase‑failure protection

Температура окружающей среды: -5℃ to +55℃ (non‑condensing); altitude ≤ 2000 м

Типичные применения & Selection Notes

  1. For direct starting, star‑delta starting, and soft‑starting of 40kW (380–440V) / 22kW (200–240V) three‑phase asynchronous motors
  2. Selection must confirm: coil voltage, number of auxiliary contacts, control circuit voltage, номинальный ток, duty category (AC‑3/AC‑1), and whether surge suppressors are required
  3. Comparable competitive models: Schneider LC1‑D80, ABB A145‑30‑11, Siemens 3RT2036

Model Example & Замена

Model designation: SC‑E4 AC220V (AC coil); SC‑E4/G DC24V (DC coil)

Replacement notes: Coil voltage, номинальный ток, mounting dimensions, and auxiliary contact configuration must match; DC coils cannot directly replace AC coils

Установка & Maintenance Tips

  1. Install vertically; avoid dusty, oily, or corrosive environments
  2. Use crimped terminals for main circuit cables; follow torque specifications in the manual; control circuit wires ≤ 2.5 мм²
  3. Regularly inspect contact erosion, loose wiring, and abnormal odors from the coil; replace main contacts or the entire contactor if necessary
  4. Connect RC circuits or varistors in parallel to suppress coil surge and protect PLC output points

Cross‑Brand Model Cross‑Reference & Replacement Guide for Fuji SC‑E4

The following cross‑reference is based on the core parameters of the Fuji SC‑E4, categorized into international first‑tier brands, Japanese/Korean equivalent brands, and mainstream domestic brands.

Two types are distinguished:

Performance‑matched (fully matching parameters, universal function)

и

Direct interchangeable (compatible mounting dimensions and terminal positions, replaceable without cabinet modification).

Key Notes for Cross‑Brand Replacement

  1. Coil specification must be 1:1 matched: AC coils (AC110V/220V/380V) and DC coils (DC24V/DC110V) cannot be interchanged. SC‑E4/G DC type can only be replaced by the same DC voltage model.
  2. Auxiliary contact logic matching: SC‑E4 has no built‑in auxiliary contacts. If the replacement model includes aux contacts, verify NO/NC logic in the PLC program to avoid malfunction.
  3. Thermal relay compatibility: Confirm rated current and mounting style after replacement; direct‑mount thermal relays must match the contactor frame.
  4. Cabinet space: Direct‑interchangeable models can be installed without modification. For performance‑matched models, verify width, высота, and depth to avoid door interference or busbar conflict.
